HAY-Leanna.

To all whom it may concern:

Be it known that I, EDWARD Mowmr, a citizen of the United States, residing at Sterling, in the county of 'Whiteside and State of Illinois, have invented certain new and useful Improvements in HayLoaders, of which the following is a full, clear, and exact specification.

My invention relates to hay loaders.

It has for its object to provide a light and stroi'ig hay loader adapted to operate elliciently inider service conditions and of such a cl'iaraetcr as to withstand long use in service. I attain these objects by the provision of an improved hay loader construction wherein. the rakes are mounted on an improved frame and, controlled in an improved manner, the several other cooperating parts of the device being likewise specifically improved as hereinafter set forth.

In the accompanying drawings I have shown one embodiment which my invention may assume in practice. It is to be understood. however. that the form illustrated herein. is chosen for purposes of illustration and may be modified.

The ends of the transverse member 18 extend beyond the carrier guides 15 and are provided with openings therein. The sides of the elevator framealsoinclude upper angle steel members 20 disposed" parallel with members 17, spaced apart therefrom and having their .lowei' ends secured by braces to the'substantially vertical U-shaped frame member 10, and extending rearward therefrom ai'e curved downward and their middle portions secured by braces to'the transverse elevator frame member 18. 21 represents a transversely disposed carrier supporting shaft at the upper'eud of the elevator frame, and having chain supporting sheaves 21 journaled thereon in a common way, and.having its opposite ends secured to carrier adjusting ends 22.

The rods 22 are slidablymounted in bracket members 23, "which brackets include centrally and longitudinally arranged side members 24 having-car members 25 at oppo-' site ends thereof that receive the carrier adjusting rods 22.

The bracket members are secured to"the upper and lowerelevator frame members by means of leg members 26 which diverge inwardly and rcarwardly from opposite ends ofthe side members 24. The lower rear ends of the adjusting rods 22 are threaded, and 27 represents adjusting nuts thereon upon the-frontsides'of the lower ear/members, whereby the rods may be secured in-any desired position of adjustment.

'The frame members 20 and 1 7 are connected together by means of four pairs 'of angularly arranged truss members .28, having their upper overlapping ends secured to the upper frame members 20, andtlicii," lower diverging ends to the lower frame members 17; one pair of the truss members 28 being preferably located at the lower end of the frame members 17, asecond pair intermediate the U-shaped member 19 and the lower end of the member 17, a third pair.

The shields are twisted outward neartheir middle in substantially. a horizontal plane, having the turned portion made concentric to the axis of the carrying wheels and supported by being ,secured to triangular bracket 111embers-35 that are secured to the rear ends of the side members 3 of the wheel frame 1, upon op )osite sides of the machine.' 36 represents a Ll-shaped frame member located in rear of the carrying wheels, having the front ends of its side members 37' pivotally connected with the driving axle 4; the frame being supported by means of rods 38, having their upper ends received by the openings in the extended ends of the trans verse frame meinbcr I8, and their lower ends connected with short chains '39 that: engage with hook membersO secured to the rear ends of the side members 37 of the U- shaped frame member 36, whereby they position of said frame maybe adjusted relative to the ground. '41 represents depending bracket members secured to the side frame members 37, and having secured to their lower ends bearing boxes 42, in which is jou'rnaled the axle 43 of a raking cylinder 44, the cylinder deriving motion from ,means including ion a sprocket chain 46, a sprocket wheel 47, and gear wheel 48 carried by the frame member 36. The raking cylinder 44 includes a common form of head inembers'49 secured to opposite ends of the axle l3, cwrrying a series of pivoted rake bars 50, Saving resilient grake teeth 51 secured tlie'reto; the rakes l niging provided with crank arms 52 at one end -that arecontrolled by a fixed earn 53 in amanner to cause the rake bars to turn 11!; about their axes and maintain theteeth in proper working position during the cycle of their rotative movement. Heretofore such rake 'controllil'ig cams have been sol formed that the teeth would be turned in a manner to be released from the hayas it i was being delivered to the lifting mechanism, the cam being flattened more or less upon its front side for that purpose. In my improved cam the rear half :i-l is made substantially semicircular but eccentric to the, axis of the raking cylinder, and terminates in a substantially straight portion 55 that is inclined forward and upward and merges into a substantially straight frontportion-l so 56 that inclines rearward and upward at the same angle with the major axis C 1) as the portion the cam being elongated forward of the center of the rear concentric portion. the major axis of the cam being inclined'downward and forward toward the. ground line.

In explanation. referring to Fig. 2, the line A- -B is a horizontal or ground line, the line Cl) is the major axis of the cam inclined dowmvard and forward at an angle of approximately 21?, degrees from the ground line. The lines E F and (il l re iresentthe angle of inclination for the major axis CD of the cam of the straight portions55 and 56, respectively, which angle is approximately 42 degrees. In other words, the parts 55 and 56 are the sides of an isosceles triangle, having the diameter of the concentric rear part 54 of the cam, or its minor axis, as a, base, and the major axis bisectin g it.

With this imprw an fOLu of cam the rake bars are controlled in a manner to cause the teeth to move in substantially a horizontal plane while raking the hay from the ground, and to be quickly turned backward to release them from their load as it is delivered to the elevator mechanism.

In Fig. 7 is shown adiagram of the cylinder head, rakingteeth and cam, illustrating the various positions of these parts as they advance over the ground in operation. The elliptical line'L-J represents the path of movement of the teeth at the lower side of the cylinder. The oval line KL indicates the path through which the teeth move at the forward or'elevating side of the cylinder, and the parabolic curve M N indicates the ath followed. by the teeth at the rear side of the cylinder when they are being returned to raking position. It will be noted that the raking position of the teeth is a prolonged one, the ends of the teeth following an elliptical path foran extended period. At the elevating side of the cylinder the teeth. are thrust outwardly to better support the hay, and when they have reached the proper point of discharge they are drawn directly rearward longitudinally. A better dumping of the hay is thus obtained. It is also to be noted that the cam member, being provided with continuous spaced walls, between which the crank arms fit, holds the teeth rigid at all times and a different operation occurs from that in whicl'i the teeth are permitted to swing freely at the upper side of the cylinder, thereby not turning over in. their orbital movement.
